METHOD AND APPARATUS FOR TAKING UP RECORDING TAPE

摘要

A method and apparatus for taking up a tape on a takeup reel mounted on a spindle from a supply reel mounted on a spindle by driving spindles and disposing the supply reel, the take-up reel and a tape transport passage therebetween in gastightly sealed enclosure, evacuating the gases in enclosure by means of a vacuum pump to a reduced pressure, and taking up the tape on the take-up reel at high velocity in the thin atmosphere the apparatus comprising a depressurized chamber with a tape inlet port formed through one wall thereof, a gas evacuating means for evacuating the chamber and a drive shaft for rotating the spindle, whereby the tape which has been guided through the tape inlet port into the depressurized chamber is taken up on the take-up reel while the pressure in said depressurized chamber is reduced.
